20 Claims.

This invention involves a machine for making sanitary napkins and relates particularly to improvements in mechanism whereby elongated pads of absorbent material are severed from the forward end of a strip of absorbent material intermittently fed in a given direction, and are individually transferred to and deposited lengthwise of a strip of gauze continuously fed alongside the strip of absorbent material and in a direction opposite to the direction of movement of the strip of absorbent material.

The mechanism of the present invention has been designed for the purpose of utilizing a strip of suitable absorbent material A intermittently fed from a roll1 of absorbent material B. From the forward end of the strip A pads C are severed by means of a continuously rotating cutter D operated by an electric motor E, the motor and cutter being so arranged as to reciprocate in a vertical direction to and from the strip. Upon being severed from the advancing end of the strip A, the pads C are delivered to a conveyer mechanism F which transports them to a depositing mechanism G by which they are delivered to alining means H supported above a strip of gauze I fed from a roll J continuously alongside the strip of absorbent material A and in a direction opposite to the direction of feed of the strip A. The strip of gauze I, with the pads C located at intervals thereon, is fed forwardly to a folding device K by means of which the edges of the strip are folded over the spaced pads C. The gauze strip, with the pads enfolded thereby, is then engaged by a gauze feeding mechanism L whereby it is delivered to the severing mechanism M which severs the folded gauze strip between the pads C, after which the gauze encased pads are deposited upon a conveyer N for removal from the machine in such manner as may be desired.

Power for operating the various mechanisms of the machine other than the continuously rotating cutter D is obtained from an electric motor O, the shaft P of which extends to a gear box Q from which the main drive shaft R of the machine extends. The various parts of the machine are carried by a suitable frame S.

In the construction herein illustrated, the roll of absorbent material B is supported in a suitable bin I carried by the frame S and having side walls and inclined bottom walls. The upper run of a feed belt 2 passing over one of the inclined bottom walls 3 operates to feed the strip of absorbent material A intermittently from the roll B. The belt 2 passes over a pair of rollers the lower one of which 4 is supported in suitable bearings in brackets 5 secured to the frame of the machine and the upper one of which 6 is also supported in suitable bearings in the frame and is intermittently driven by means of a sprocket chain 'I passing over a sprocketwheel 8 fixed to the shaft of the roller 6, also over a drive sprocket 9 on the extended end of a shaft I0 carrying a roller II for the feed belt for the strip of absorbent material A. The shaft III is supported in bearings in bracket arms I2 bolted or otherwise secured on the frame.

As the strip of absorbent material A is fed upwardly from the bin I by the belt 2 it is delivered to and fed forwardly by the opposing runs of an upper feed belt I3 and a lower feed belt I4. The upper belt I3 passes over idler rolls I5, EE and an intermittently operated drive roll I1 ,which receives its motion through the intermittent mechanism I8 as shown in Figs. 8 and 10. The drive roll Il is xed upon a shaft I9 supported in bearings in the upper ends of brackets 2i) suitably is fixed on one end of a shaft 2| mounted below shaft I'I in bearings in the brackets 20. The shaft 2| is continuously driven by a sprocket chain 22 engaging a sprocket wheel 23 thereon and a sprocket wheel 24 on the main drive shaft R.

The lower feed belt I4 passes over idler rolls 25, 2B and the intermittently operated drive roll II on the shaft IB heretofore referred to. The shaft I0 is driven by a sprocket chain 21 which engages a sprocket wheel 28 thereon, also a driven sprocket wheel 29 on shaft I9,.and passes over an idler sprocket wheel 30 on stub shaft SI supported in a suitable bracket on the frame.

As the strip of absorbent material A is thus fed forwardly over the bed plate 32 it is subjected to the operation of a pair of cutting dies 33 substantially triangular in cross section as shown in Figs. 13, 14 and 15. These dies are mounted upon and project downwardly from a supporting plate 34 of the pad cutting mechanism and cooperate with suitable die plates 35 supported upon the frame of the machine inwardly of the opposite edges of the strip of absorbent material A. The supporting plate 34 is mounted upon the upper ends of two pairs of guide bars 35 mounted for vertical reciprocation in hollow guide members 3? bolted or otherwise secured to the frame of the machine as shown in Figs. 14 and 15.

A cross head 38 is mounted upon the lower ends of the tWo pairs of reciprocating bars 36, and pivoted thereto and extending downwardly therefrom is a. connecting rod 39 the lower end of which is connected to a crank 4I) on a shaft 4I mounted in bearings in brackets 42 on the main frame S and continuously driven by means of a sprocket chain 43 in engagement with a sprocket wheel 44 thereon and a sprocket wheel i5 on the main drive shaft R.

The motor E by which the rotary cutter D is continuously operated is mounted upon the supporting plate 34. Fixed to the supporting plate 34 is a guard member 46 for the cutter D. Projecting from the guard member 46 is an elongated lug 4'! having spaced openings extending therethrough in alinement with similar openings in an elongated lug 48 projecting outwardly from a portion of the supporting plate 34. These alined openings receive a pair of vertically movable rods 49 upon the lower ends of which a weighted presser foot 5! is mounted for the purpose of holding the forward end of the strip of aborbent material A as the pads C are severed therefrom by means of the rotating cutter D.

As will be seen from the above, the strip of absorbent material A is positively and intermittently advanced by the feed belts I3, I4 over the bed plate 32. The movements of feed mechanism for the strip of absorbent material A, and the reciprocating mechanism for the rotary cutter D and the cutting dies 33 are so timed that at the moment the strip of material A ceases to be advanced the rotary cutter D. the cutting dies 33, and the presser foot 50 are moved downwardly into contact with the strip. As the weighted presser foot 50 holds the extreme end of the strip of absorbent material A in position on the receiving end of the runway 5I of the conveyer mechanism F, the rotary knife D severs the end of the strip on the line of the V-shaped notches provided on opposite edges of the strip A upon the previous downward movement of the cutting dies 33.

As is shown in Fig. 13 of the drawings, the

weighted presser foot 50 extends downwardly slightly below the lower edge of the rotary cutter D so-that this presser foot comes in contact with the end of the strip of absorbent material A in order to hold the end of the strip in position upon the receiving end of the runway as the end of the strip is severed by the rotary cutter. Inasmuch as the weighted presser foot is supported upon the lower end of the slidable rods 49, when the presser foot contacts with the strip of absorbent material A, further downward movement thereof ceases and it rests upon the upper face of the strip of absorbent material while the rotary cutter continues its downward movement and moves upwardly in the course of its reciprocating motion, whereupon the presser foot is lifted from the then severed absorbent pad C.

The rotary cutter D is so timed with respect to the feed mechanism for the strip of absorbent material A that when the cutter` is lifted sufciently high to raise the presser foot out of contact with the pad C just severed from the advanced end of the strip A, the feeding mechanism operates to advance the strip and thus move the severed pad C forwardly on the runway 5| of the pad conveying mechanism F. At the same time, the pad conveying mechanism F is brought into operation by means of a sprocket chain 52 driven by a sprocket wheel 53 on the upper shaft I9 of the intermittent mechanism I8 and driving a sprocket wheel 54 fixed to the outer end of a shaft 55 mounted in suitable bearings in an overhanging arm 56 secured to the frame S of the machine. The inner end of the shaft 55 has fixed thereon a bevel gear 51 meshing with a bevel gear 53 on the upper end of a shaft 59 slightly inclined from the vertical and supported in a bearing on the inner end of the cverhanging arm 56. Fixed to the lower end of the inclined shaft 59 is a drive pulley 6!! about which the pad conveyer belt 6| passes. The operating portion of the conveyer belt is held in position by means of two sets of grooved guide pulleys 62 and 63, one of which is secured to the outer face of an arcuate guide arm 64 extending from immediately in front of the rotary cutter D over the advancing strip of gauze I. The conveyer belt 6| also passes over and is supported at the extreme end of its run by an idler pulley 65 mounted on the lower end of a stub shaft 66 having a bearing in the arcuate arm 56. The outer end of this arcuate guide arm 56 is supported by means of a suitable bracket 61 secured to the frame S of the machine.

The lower or operating edge 68 of the conveyer belt 5| is spaced from the runway 5| a distance slightly less than the normal thickness of the pads C so that the pads are slightly compressed when being transported over the runway by the belt. As illustrated in Figs. l to 4 of the drawings the conveyer belt 6| is circular in cross section. The belt may, however, be rectangular in cross section, as shown by the form of machine illustrated in Figs. 6 to 16, and the operating edge may be provided with serrations, or otherwise roughened as indicated at 69 in Fig. 22.

In order to assist in delivering the pads C to the conveyer belt 6| as they are severed from the forward end of the strip of absorbent material A, and in order to relieve the friction between the entering pad C and the runway 5|, a friction wheel 1! is mounted below the runway 5| upon a shaft 1| so that its operating surface protrudes upwardly through an opening 12 in the runway. The

shaft 1| is supported in a pair of bearing brackets 113, 1.4, adjustably mounted on the machine frame. The .outer vbracket v13 is preferably so mounted as to permit adjustment of the shaft 1| in a horizontal direction, and the inner bracket is so mounted as to permit adjustment of this shaft in a vertical direction, corresponding adjustments of the friction wheel 10 being thereby effected.

The shaft 1| is driven by means of a belt 15 passing over a pulley 16 xed to the outer end thereof and over a pulley 11 fixed to the outer end of the shaft 55. Inasmuch as the shaft 55 is driven intermittently, intermittent rotary movement is likewise imparted to the shaft 1| carrying the friction wheel 12. As will also be noted, the friction wheel 12, the belt conveyer 6|, and the feed mechanism for the strip of absorbent material A receive their intermittent motion from he same source.

It will be clear, therefore, from the various figures of the drawings, that when the pad severing mechanism nieves upwardly in the course of its reciprocating movement, the pad conveying mechanism and the friction wheel are simultaneously set into operation. The advancing movement of the forward end of the strip of absorbent material A operates to push the previously severed absorbent pad C upon the protruding surface of the friction wheel 1|), and thus the friction wheel operates to lift the forward the friction between the contacting surfaces of the pads C and the runway 5| and prevents the pads from being damaged by the conveyer belt 6| as they are delivered to the belt for movement across the runway 5|. Upon each successive movement of the conveyer belt 6|, the separate and spaced pads C are moved forwardly upon the runway 5| so that the position of each pad is changed from one at right angles to the moving strip of gauze I as it is delivered to the conveyer belt 6|, to a position lengthwise of said strip at the dscharge end of the runway 5|.

As the pads C are moved to the discharge end of the runway 5| by the conveyer belt 6| they are delivered to the depositing mechanism G, by means of which the individual pads are positively delivered in spaced relation lengthwise of the continuously moving strip of gauze I. The depositing mechanism G comprises a pair of substantially U-shaped carrying members 18 mounted on the inner ends of a pair of cscillatable shafts 1S suitably supported in bearings formed in the inner side wall of a gear case 86 secured on the frame of the machine. The open ends of the U-shaped carrying members 18 are oppositely arranged with respect to each other, and the lower leg 8| of the members 18, particularly the member toward the end of the machine from which the gauze is fed, is somewhat longer than the upper leg 82, so that these carrying members may K,

cured to the crank arm 83 of each shaft and the opposite end secured to a stationary support in the gear case operates to retain each of the rollers 34 in engagement with its respective semicircular cam.

Fixed to each of the shafts 86 is a gear wheel 88 meshing with a gear 89 on an intermediate shaft 90 having its opposite ends mounted in suitable bearings in the side walls of the gear case 80. The inner end of the shaft 90 extends beyond the inner wall of the gear case and has fixed thereon a sprocket wheel 9| for engagement by a sprocket chain 92 which passes over a sprocket wheel 93 fixed to the extended end of the drive shaft 4|. Inasmuch as the main drive shaft R is rotated continuously, the gear wheels 88 and 89 within the gear box 80 are likewise rotated continuously so that the semi-circular cams B5 move the U-shaped carrying members 18 intermittently to deliver to the continuously moving strip of gauze I the individual pads C received thereby from the delivery end of the conveyer belt 6|.

As will be apparent from Figs. 1, 12, 17 and 20 of the drawings, the depositing mechanism G is so constructed and is so related to the conveyer mechanism F that the pads C are delivered to the depositing mechanism by the conveyer mechanism with the ends of each pad resting upon the oppositely arranged supporting legs 8|. When the shafts 19 are rocked to withdraw the legs 8| from beneath the ends of a pad supported thereon, the upper legs 82 turn with the shafts so that their free ends engage the pad before the legs 8| have been completely withdrawn, and positively discharge it from the legs 8|. In view of the light, ufy character of the pad material, such a positively acting depositing and discharging device has been found advantageous in insuring delivery of the pads at uniform intervals upon the strip of gauze.

As illustrated herein, the depositing mechanism G delivers the individual pads C to the alining mechanism I-I comprising a pair of oppositely arranged pad guiding and directing members 94 suitably supported above the strip of gauze I and having the forward ends 95 thereof converging as clearly shown in Figs. 1 and 6 of the drawings, and the carrying members 18 are preferably positioned between the guide members 94.

The strip of gauze I is fed forwardly from the roll J which is supported in suitable brackets 96 extending outwardly from the frame S of the machine. Preferably the roll J is provided with a brake device 91, such as illustrated in Figs. 8. 12 and 20 of the drawings, in order that overrunning of the roll J may be prevented as the gauze is withdrawn therefrom. The strip of gauze I, after passing over a series of idler rolls 90, passes over the tapering mouth 99 of a channel |00 provided between oppositely arranged channel-forming members |0| secured upon the frame of the machine. As shown in Figs. 6 and 16 of the drawings, the pad alining members 94 extend downwardly into the gauze channel |00 and the tapering lower edges |02 of the alining members operate to gradually press the gauze downwardly into this channel as it moves forwardly over the ends of the channel-forming members IDI.

As shown in Figs. 16 and 22, the bottom of the gauze channel |00 is formed by a base plate |03 supported upon the frame S of the machine. The edges of the gauze strip I are maintained in contact with the upper faces of the channelforming members |0| on opposite sides of the channel |00 by means of a pair of rollers |04 supported from a bracket member |05 extending upwardly from the machine frame. The rollers |04v are supported in hangers |05 which are angularly adjustable with respect to the strip of gauze and are retained in adjusted position by Wing nuts |06, and the rollers are mounted for vertical movement in slotted bearings |07 as shown in Figs. 12 and 20.

Inasmuch as the oppositely arranged alining members 94 are located adjacent the delivery end of the runway 5| beneath the conveyer belt 6|, the individual pads C are delivered to the continuously moving strip of gauze I in such a position as to rest upon the gauze in the bottom of the channel |00 in a direction lengthwise of the strip of gauze, and as the strip of gauze moves forwardly the pads are carried along therewith beneath a resilient retaining member |08 having one end mounted upon the bracket |09 extending transversely of the gauze channel |00 and supported from the machine frame, and its opposite end floating within the gauze channel. As

the strip of gauze with the pads spaced in intervals thereon moves forwardly in the channel IGZ] the opposite edges of the strip encounter the folding device K comprising a pair of leaves having their outer edges hinged to the channel-forming members |0|. verge toward and overlap at one end of the folddevice as clearly shown in Figs. 1 and 6 of the drawings, and operate in a manner well understood in the art.

Gauze tensioning rollers are mounted upon f" the supporting brackets |09 and ||2 above the folding members ||0 for the purpose of retaining the edges of the gauze taut thereon. These rollers are similar to rollers |64 in structure and operation, and are angularly adjustable with respect to the strip of gauze in order to increase or decrease the outward tension on the edges of the gauze as may be desired, and they are mounted in slotted bearings as clearly shown in Figs. 12 and 20 in order to permit of vertical movement. An additional pressure roller H3 is mounted in a hanger ||4 adjustably suspended from a bracket ||5 supported upon the channelforming members |0| for the purpose of retaining the upper fold of the gauze in position.

As will be understood from the showing in Figs. 1, 5 and l2 of the drawings, the strip of gauze I emerges from the folding device K with the pads C spaced at intervals thereon and with the opposite edges thereof folded over the upper faces of the pads C in overlapping relation with respect to each other. The strip of gauze thus folded about the pads is then delivered to the gauze feeding mechanism. This mechanism comprises essentially upper and lower endless belts ||6 and between the opposing runs of which the gauze enclosed pads are fed. The upper belt ||6 passes around a drive roll H3 at one end and the opposite end thereof passes about an idler roll |9 mounted in bearings on the outer ends of arms |20 pivoted upon the shaft |2| of an idler` roll |22 over which the upper run of the upper belt passes.

The lower belt passes around a driving roll |23 fixed on a shaft |24 having the opposite ends thereof supported in bearings in brackets |25 upstanding from the frame S of the machine. The roll |23 is driven by means of a gear wheel |26 fixed to the shaft |24 thereof and meshing with a gear wheel |21 fixed to the shaft |28 of These folding members con- 5 the roll ||8 mounted thereabove in the brackets |25. The opposite end of the lower belt passes over an idler roll |29 having the opposite ends of its shaft |30 mounted in bearings in brackets |3| on the frame of the machine. The intermediate portion of the upper run of the lower belt passes over an idler roll |32 on a shaft |33 having the opposite ends thereof mounted in bearings in a pair of brackets |34 extending upwardly from the machine frame and also supporting the shaft lili of the roll |22.

Both the upper and lower gauze feed belts I5, Il are continuously driven by means of a sprocket chain |35 passing over a sprocket wheel |35 xed on the shaft |28 of the roll IIS, also over a sprocket wheel |31 xed on one end of an extended shaft |38 mounted in bearing brackets |39 on the machine frame. A second sprocket |49 on this shaft is engaged by a sprocket chain I4! passing over a sprocket wheel |42 on the main drive shaft R so that continuous movement is given to the gauze feed belts.

The shaft E38 has secured thereon a cutter blade |43 which at each rotation thereof is brought into shearing Contact with a cooperating cutter blade |453 secured in a suitable manner to the machine frame. This cooperating cutter blade is located at the discharge end of the gauze feed belts H5, IH, and the rotary movement of the cutter blade |43 on the shaft |38 is so timed with respect to the speed of the gauze as to sever the folded strip of gauze between the successive pads enfolded thereby.

Upon being severed from the continuous strip of gauze by the cutter blade |43, the completed napkins are delivered to the conveyer N with the ends of the length of gauze envelope extending beyond the ends of the encased pad C as shown in Fig. 25. 'Ihe conveyor N is arranged to deliver the napkins to any convenient location Whereupon the extended ends of the gauze envelope are folded inwardly in overlapping relation upon the pad and the napkins are then packaged in any suitable manner.

In the embodiments of the invention heretofore referred to, the improvements have been described in connection with a form of machine in which the pads severed from the forward end of the advancing strip of absorbent material A are deposited upon a stripof gauze arranged alongside the strip of absorbent material and moving continuously in the opposite direction. In Fig. 18 there is disclosed a form of the machine in which the pads C arey deposited upon a strip of gauze moving in the same direction as the strip of absorbent material. The pad conveying mechanism heretofore described is equally applicable to a machine of this character.

Fig. 19 discloses a slightly modified form of pad conveying mechanism. In the machine shown therein, the strip of gauze is moved continuously alongside the strip of absorbent material and in the same direction. The pad conveying mechanism, however, is so constructed as to move the pads C in the direction of their length over the runway 5| in order that they may be deposited upon and lengthwise of the strip of gauze. As illustrated in Fig. 19, the friction wheel '10 is arranged parallel to the rotary cutter D instead of substantially perpendicular thereto as shown in the modifications heretofore described. In this case, therefore, the friction wheel 10 operates to give to the pads C an initial movement in the direction of their length imend of the strip of absorbent material. The pads are then engaged between the conveyer belt 6| and the runway 5| and move forwardly over the runway, in the direction of their length, and discharged through a suitable opening |45 in the runway upon vthe continuously moving gauze strip I.

In Figs. 20 and 21 a modified form of gauze feeding mechanism is disclosed in which the upper feed belt I6 does not differ materially from the feed belt I6 heretofore described. The lower feed belt Ill', however, is arranged to extend substantially throughout the length of the machine beneath the gauze channel |90 upon the bed plate |93. Adjacent the tapering channel mouth 99 f-eed belt H1 passes over a roll |45, and the lower run of the belt is provided with a suitable tension roll |45. This belt is guided on the bed plate |03 in undercut grooves |41 in the channel-forming members In this form of the invention the outer ends of the'pivot arms |20 are limited in their movement in a downward direction by the engagement of the extended ends of the shaft or roll ||9 or other suitable means with the open bearings |48 formed on the upper ends of the upstanding brackets |49. This construction limits the extent to which the roll H9 may move toward the roll |29, but permits the outer ends of pivot arms |20 to move upwardly away from the lower feed belt in case an unusual thickness of material accumulates between the belts.

As disclosed in Figs. 20 and 22 of the drawings the pad conveyer belt Bla is rectangular in cross section and is provided with a longitudinally extending channel |Il which engages with cooperating flanges |5| on the guide pulleys B2. This construction operates to retain the conveyer belt in proper position upon the guide pulleys.
